' Application filed September 27, 1912. Serial No. 722,672.

To all whom, it may concern:

Be it known that I, LOUIS J. REMMELE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Door-Stops forRailway-Cars; and I do hcrebydeclare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to characters ofreference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements in doors forcars; and, the present invention relates, more particularly, to anarrangement of sliding doors, located at the intersections of theend-portions of the carbody and the platforms thereof, provided withsuitable means for retaining the door-sections in either their closed oropened relations, but without interfering with the opening or closingmovements of the doorsections.

The invention has for its principal object to provide a novelarrangement of sliding doors for street-railway and other cars, combinedwith means for retaining the doors in their opened or closed relations,but without interfering with the opening or closing movements of thedoors, said means being arranged and constructed with a view ofpreventing any sliding movements of the doors or door-sections, when intheir opened or closed relations, due to the lateral or other motions ofthe car-body, caused by the vibrations of the car when running rapidly.

Other objects of the present invention will be clearly understood fromthe following detailed description of the present invention.

With the various objects of the present invention in view, the saidinvention consists, primarily, in the novel arrangement of sliding doorsor door-sections for cars, and means cooperating therewith for retainingthe doors ordoor-sections in their opened or closed relations, withoutinterfering with the sliding movements of the doors or door-sections, soas to permit the doors or,doo-r-sections to be easily operated to bringthem into their opened or closed posit-ions; and, the inventionconsists, furthermore, in the novel arrangements and combinations of thevarious devices and parts, as well as in the details of the constructionof the same, all of which will be more fully described in the followingspecification, and then finally embodied in the view showing a part ofthe end-casingbroken away, and illustrating, also in elevation, themanner of slidably hanging the said door-sections, and one of thedevices or door-stops for retaining the door-sections in their closedrelation. Fig. 2 is a transverse vertical section, on an enlarged scale,said section being taken through the hollow enclportion of the body ofthe car, in which the said door-sections are slidably mounted, said viewillustrating in connection therewith,

and in elevation, the upper portions of the slidably mounteddoor-sections, sheaves secured to said door-sections, a rail upon whichsaid sheaves are supported so as to be adapted to roll thereon, andvariously formed devices or door-stops, with which some of said sheavesare adapted to separably engage, so as to retain the doors ordoor-sections in their closed or their opened relations. Fig. 3 is adetail vertical section taken on line 33 in said Fig. 2, looking in thedirection of the arrow :12; and Fig. 4 is a horizontal sectionalrepresentation taken on line 44 in said Fig. 2, looking in the directionof the arrow y.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

Referring now to the said figures of the drawings, thereference-character 1 indicates a portion of the body of any usual typeof street railway car, and 2 and 3 indicate, respectively, the usualouter and inner walls of either end of the car-body, said walls beingformed with the usual space between them, and having an opening, as at,to permit passengers to enter from the platform into the body of thecar, or from the latter onto the platform. The upper part 5 of the saidopening in the outer wall 2 is closed in the usual and well-knownmanner, and in the inner wall 3 this portion is closed by means of theusual transom-like member or element, as 6, of which only a portion isshown in Fig. 1 of the drawings, said member or element 6 being hinged,as at 7, to said wall 3, so as to be adapted to swing in a downwarddirection, and being held in its closed position by means of a suitablyconstructed locking device or catch, as 8. Suitably secured within saidhollow space between the said walls 2 and 3 are a pair of suitablyconstructed brackets, as 9, and suitably connected with said bracketsare the respective end-portions of a laterally extending bar 10 whichforms a rail upon which the rollers 11 of the usual sheaves 12 aremounted and are adapted to roll thereon, in either direction. The usualdoors or door-sections, as 13, are slidably suspended from said rail 10by means of the said rollers 11 and sheaves 12, as will be clearlyunderstood from an inspection of said Figs. 1 and 2 of the drawings.Located within the hollow space between the said walls, and at suitablepoints above the said rail 10, are suitably constructed retainingdevices or door-stops, as 14, 15, 16 and 17, each pair of said devices14.- and 15, and 16 and 17, being respectively right and left devices,and while the general arrangement of the parts of the stops 14k and 15is practioally the same as the general arrangement of the parts of thestops 16 and 17, still there is a slight difference of constructionbetween the parts of the stops 14 and 15 and the parts of the stops 16and 17.

Referring now to the right and left doorstops 14 and 15, it will be seenthat each door-stop consists, of a back-plate 18, provided withperforations for the reception of screws 19, by means of which the saidstops are secured in place. Extending along its upper marginaledge-portion, each backplate 18 is made with a longitudinally extendingflange, as 20, extending at a right angle, or approximately so, from theface of said back-plate, and extending in a downward direction, at rightangles, or approximately so, from a part of the marginal edge-portion ofthe flange 20, is a plate-like portion 21. Connected with the saidplatelike member or portion 21, and the backplate 18, so as to extenddirectly across the space between the said parts, is a pintle orpivot-pin 22. Upon the pintle or pivot-pin 22 of each doorstop 14 and 15is arranged so as to be adapted to swing thereon, an eye-portion 23 of asuitably formed bellcrank, comprising an upwardly projecting finger orarm 24, and a laterally extending arm 25, said arm being formed with alower receiving and retaining depression,

as 26, which is preferably of a concave eonfiguration, as shown.Connected with the upper portion of each upwardly projecting finger orarm 24 and also with each flange 20, substantially as shown, aresuitable eyebolts, as 27 and 28, or other suitable fastening means,between which are arranged, with their end-portions secured to saideyebolts 27 and 28, suitably coiled springs 29, the initial tendency ofsaid springs being to force the said fingers or arms 24 against suitablestops or pins, as 30, with which the parts are provided, and whereby thenormally supported position of each bell-crank is that represented insaid Fig. 2 of the drawings, and the tendency of the arms 25 is to movein downward directions, whereby the rollers 11 of the sheaves 12, asthey roll into engagement with the convex portions 31 of said arms 25,as the doors or doorsections are brought into their closed relation,will cause said arms 25 to be raised, until the rollers 11 reach thedepressions 26, and the springs 29 will thereupon cause the parts tocoact to retain the doors or door-sections in their closed relation.

It will also be seen from an inspection of the drawings, that eachdoor-stop 16 and 17 consists of a back-plate 32 pro-vided withperforations for the reception of screws 33 by means of which the saidstops are secured in their respective places, and in a manner asindicated in said Fig. 2 of the drawings. Extending along its uppermarginal edge-portion, the back-plate 32 is also made withalongitudinally extending flange, as 34, extending at a right angle, orapproxi mately so, from the face of said back-plate, and extending in adownward direction, at right angles, or approximately so, from a partofthe marginal edge-portion of said flange 34, is a plate-like port-ionConnected with this plate-like portion 35 and the back-plate 32, so asto extend directly across the space between the said parts, is a pintleor pivot-pin 36. Upon said pintle or pivot-pin 36 of each door-stop 16and 17 is arranged so as to be adapted to swing thereon, an eye-portion37 of a suitably formed bell-crank, comprising an upwardly projectingfinger or arm 38, and a laterally extending arm 39, said arm 39 beingformed with a lower receiving and retaining depression, as 40, whichalso is preferably of a concave configuration, as shown.

Connected with the upper portion of each upwardly projecting finger orarm 38, and also with each flange 31, substantially as shown, aresuitable eye-bolts 41 and 12, or other suitable fastening means, betweenwhich are arranged, with their end-portions secured to said eye-bolts 11and 42, suitably coiled springs 43, the initial tendency of said springsbeing to force the said fingers or arms 38 against suitable pins orstops, as a l, with which the back-plates 32 are provided, and wherebythe normally supported position of each bell-crank is that represent edin said Fig. 2 of the drawings, and the tendency of the arms 39 is tomove in downward'directions, whereby the rollers'll of the sheaves 12,as they roll into engagement with the convex portions 45 of said arms39, as the doors or door-sections are brought into their openedrelation, will cause said arms 39 to be raised, until the rollers 11reach the depressions 40, and the springs 43 will thereupon cause theparts to co-act to retain the doors or door-sections in their openedrelation.

From the foregoing description of my present invention it will beevident that I have devised a simply constructed and readily operatingmeans in the form of a doorstop, which will hold the door or doorsectionin either its closed or opened relation, but will still permit of thedoor or door-section tobe operated in either direction. The door-stopsare also arranged in such a manner, so that where two door-sections areused, as in the present case, the doors or door-sections may beindependently moved, or may be operated simultaneously.

I am aware that some changes may be made in the general arrangements andcombinations of the various devices and parts, as well as in the detailsof the construction of the same, without departing from the scope of thepresent invention as set forth in the foregoing specification and asdefined in the clauses of the claim which are appended to the saidspecification.
